--- title: Mancer Provider Guide description: Mancer on NeuroLink — OpenAI-compatible Tier-2 catalog provider, default model `deepseek-v4-flash` keywords: mancer, mancer-tech, openai-compatible, tier 2, provider setup --- # Mancer Provider Guide Mancer is a **Tier-2 catalog provider**: OpenAI-wire-compatible with no behavioural quirks, so its entire integration is one JSON file (`src/lib/providers/catalog/mancer.json`) rather than hand-written code. That file is the source of truth for everything on this page. --- ## Key Facts - **Provider id**: `mancer` (aliases: `mancer-tech`) - **Protocol**: OpenAI-compatible (`/chat/completions`) - **Base URL**: `https://neuro.mancer.tech/oai/v1` - **Default model**: `deepseek-v4-flash` - **Models in catalog**: 10 - **Streaming**: supported - **Tool calling**: **not supported** - **Structured output**: supported - **Embeddings**: not supported - **Billing**: free-tier - **Key format**: `^mcr_[A-Za-z0-9]+$` --- ## Quick Start ### 1. Get an API key 1. Visit: https://mancer.tech/dashboard and sign in 2. Create an API key (prefix mcr\_) 3. Without credits only the free model 'mytholite' answers; every other model returns 402 until you add credits at https://mancer.tech/pricing 4. Set `MANCER_API_KEY` in your .env file ### 2. Configure ```bash export MANCER_API_KEY=your-api-key export MANCER_MODEL=deepseek-v4-flash # optional — overrides the default model export MANCER_BASE_URL=https://neuro.mancer.tech/oai/v1 # optional — self-hosted or proxy ``` ### 3. Use it ```typescript import { NeuroLink } from "@juspay/neurolink"; const neurolink = new NeuroLink(); const result = await neurolink.generate({ input: { text: "Explain context windows in one paragraph." }, provider: "mancer", model: "deepseek-v4-flash", }); console.log(result.content); ``` ```bash # CLI npx @juspay/neurolink generate "Hello" --provider mancer ``` Per-request credentials work as they do for every provider: ```typescript await neurolink.generate({ input: { text: "Hello" }, provider: "mancer", credentials: { mancer: { apiKey: process.env.MANCER_API_KEY } }, }); ``` --- ## Models | Model | Context | Vision | $/M in · out | Notes | | ------------------------ | ------- | ------ | ------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | `mythomax` | 8K | no | $0.14 / $0.24 | MythoMax (LLaMA 2, Simplified Alpaca format) — pricing and limits from the authenticated /oai/v1/models roster, 2026-09-03 | | `deepseek-v4-flash` ⭐ | 1M | no | $0.07 / $0.2 | DeepSeek V4 Flash — Mancer's flagship general model; paid credits required — pricing and limits from the authenticated /oai/v1/models roster, 2026-09-03 | | `deepseek-v4-flash-0731` | 1M | no | $0.07 / $0.2 | DeepSeek V4 Flash, 2026-07-31 snapshot; paid credits required — pricing and limits from the authenticated /oai/v1/models roster, 2026-09-03 | | `mytholite` | 3K | no | $0 / $0 | MythoLite — Mancer's free demo model (2,560-token context, 150-token completions, Simplified Alpaca format); the only model usable with a zero balance — pricing and limits from the authenticated /oai/v1/models roster, 2026-09-03 | | `remm-slerp` | 6K | no | $0.14 / $0.26 | ReMM-SLERP (Simplified Alpaca format) — pricing and limits from the authenticated /oai/v1/models roster, 2026-09-03 | | `magnum-72b-v4` | 32K | no | $1 / $2 | Magnum 72B v4 (ChatML format) — pricing and limits from the authenticated /oai/v1/models roster, 2026-09-03 | | `glm-4.7` | 128K | no | $0.28 / $1 | GLM-4.7 — pricing and limits from the authenticated /oai/v1/models roster, 2026-09-03 | | `gpt-oss-120b` | 128K | no | $0.022 / $0.2 | GPT-OSS 120B — pricing and limits from the authenticated /oai/v1/models roster, 2026-09-03 | | `weaver-alpha` | 8K | no | $0.16 / $0.3 | Weaver Alpha (Simplified Alpaca format) — pricing and limits from the authenticated /oai/v1/models roster, 2026-09-03 | | `dans-pe-1.3-24b` | 32K | no | $0.2 / $0.8 | Dan's PersonalityEngine 1.3 24B — pricing and limits from the authenticated /oai/v1/models roster, 2026-09-03 | **Fallback order** when the default is unavailable: `deepseek-v4-flash` → `gpt-oss-120b`. --- ## Verification status Tier-2 onboarding requires evidence before a provider is accepted, and `pnpm run verify:provider-onboarding` gates it in CI.
